6E- Mutations
6G- Meiosis
6F- Genetics

Mutations

• Harmful - Causes an enzyme or protein to not function properly

• Helpful - Causes a genetic change that is good for the individual/species

• Neutral (not good or bad) - Doesn't do anything

Multiple Choice

A point mutation is usually what type of mutation

• Frameshift

• Insertion

• Deletion

• Substitution

Multiple Select

A frameshift mutation is which of the following?

• Point mutation

• Insertion

• Deletion

• Subtitution

Multiple Choice

Which mutation would be more harmful for an organism?

• Point mutation (substitution)

• Frameshift (insertion/Deletion)

Multiple Choice

Why would a frameshift be more harmful?

• It changes all the code downstream

• Only one nucleotide is changing

• All mutations are harmful

• It can't correct iself

Open Ended

6F Mice have two unlinked allele pairs that affect fur color. The table shows how allele pairs affect fur color. The term “agouti” describes fur with pigmentation that changes in each hair from the shaft to the tip, giving the fur a banded appearance. Mice with the aa allele pair are albino, regardless of the second allele-pair combination.

What is the probability of albinism in the offspring of a cross between two mice with AaBb alleles?
